!
CAUTION:
Before touching leads, connectors, pins, and other components
when handling the circuit board, use a properly grounded wrist
strap to prevent damage from electrostatic discharge (ESD).
Installing the Processor in the Carrier
To install the processor in the carrier, follow the steps below. Refer to
Figure 2–10.
!Remove the protective cover from the gold-finger connector on the
back of the processor.
!Lower the hook on top of the processor module onto the rod on top
of the carrier in Slot 0, the first slot next to the power supply.
!Make sure that the connector on the module mates properly with
the connector on the carrier as you swing the processor down into
place.
!
CAUTION:
To avoid damage, do not force the module. If the module does not insert
easily, press the bottom rear locking tab, remove the module, and inspect
the module and carrier for damage or obstruction. The bottom-rear locking
tab is shown in Figure 2–10. This tab is used on all modules.
If there is no damage and no obstruction, reinsert the module.
A damaged carrier or module must be replaced.
!Push firmly until the processor snaps into place.
The processor should be securely attached to the carrier and locked in
place by the locking tab on the bottom rear of the processor.
